Answer:
7500 or 14700 square yardsStep-by-step explanation:
Let the sides be x and y
3 sides sum to
2x + y = 350 orx + 2y = 350If one side is 3 times the other then we have
x = 3yThe sums above become:
2x + y = 350 ⇒ 2(3y) + y = 350 ⇒ 7y = 350 ⇒ y = 50 and x = 150x + 2y = 350 ⇒ 3y + 2y = 350 ⇒ 5y = 350 ⇒ y = 70 and x = 210The area in each case is:
50*150 = 7500 square yards70*210 = 14700 square yardsblem Read Aloud and Instructions Jada is looking to earn some extra money over summer break so she starts a babysitting service with some of her friends. The babysitting service charges a flat fee of $10 to book a babysitter and then charges a different amount per hour based on which person is babysitting. Jada earns d dollars per hour and works for h hours one night. Her total earnings, T. can be represented by the equation: T= dh + 10 Write the equation that can be used to easily find the amount of hours. h. Jada worked if we know her hourly rate, d, and her total earnings,
the equation of total earning by jada is
T = dh + 10
here, h = hours, d = dollars per hour, and T = total earning
Now,
\(\begin{gathered} T-10=dh \\ h=\frac{T-10}{d} \end{gathered}\)so the answer is h = (T-10)/d
3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

If you plan to pay off a loan of $5,800 by submitting $250 per month, how many months will it take you to pay this debt off entirely and how much will your final payment be?
Answer:
24 months. Your final payment would be $50
Step-by-step explanation:
5800/250 gets you 23.2 but you can't have half of a month so, it would take 24 months. 250*23 makes 5750. 5800-5750 gets you 50. Your final payment would be $50
Answer: At least 24 months, with a final payment of 50 dollars on the 24th month.
Step-by-step explanation:
5,800/250 = 23.2
An easier way to do this is get this answer, and then multiply 250 by 23 which gives you ($)5,750, then just subtract that from $5,800 leaving you with 50, which is your last payment which is where the .2 comes from. Meaning it will take 24 months at the least, giving you $50 as your final payment.

Answer:
-72x - 53y + 287 = 0.
Step-by-step explanation:
To find the equation of the image of the circle, we need to reflect each point on the circle in the given line mirror.
The line mirror equation is given as 4x + 7y + 13 = 0.
The reflection of a point (x, y) in the line mirror can be found using the formula:
x' = (x - 2Ay - 2B(Ax + By + C)) / (A^2 + B^2)
y' = (y - 2Bx + 2A(Ax + By + C)) / (A^2 + B^2)
where A, B, and C are the coefficients of the line mirror equation.
For the given line mirror equation 4x + 7y + 13 = 0, we have A = 4, B = 7, and C = 13.
Now, let's find the equations of the image of the circle.
The original circle equation is x² + y² + 16x - 24y + 183 = 0.
Using the reflection formulas, we substitute the values of x and y in the circle equation to find x' and y':
x' = (x - 2Ay - 2B(Ax + By + C)) / (A^2 + B^2)
= (x - 2(4)y - 2(7)(4x + 7y + 13)) / (4^2 + 7^2)
= (x - 8y - 8(4x + 7y + 13)) / 65
= (x - 8y - 32x - 56y - 104) / 65
= (-31x - 64y - 104) / 65
y' = (y - 2Bx + 2A(Ax + By + C)) / (A^2 + B^2)
= (y - 2(7)x + 2(4)(Ax + By + C)) / (4^2 + 7^2)
= (y - 14x + 8(Ax + By + C)) / 65
= (y - 14x + 8(4x + 7y + 13)) / 65
= (57x + 35y + 104) / 65
Therefore, the equation of the image of the circle is:
(-31x - 64y - 104) / 65 + (-57x + 35y + 104) / 65 + 16x - 24y + 183 = 0
Simplifying the equation, we get:
-31x - 64y - 57x + 35y + 16x - 24y + 183 + 104 = 0
-72x - 53y + 287 = 0
So, the equation of the image of the circle is -72x - 53y + 287 = 0.
Suppose the U.S. president wants an estimate of the proportion of the population who support his current policy toward revisions in the health care system. The president wants the estimate to be within 0.02 of the true proportion. Assume a 99% level of confidence. The president's political advisors estimated the proportion supporting the current policy to be 0.41. A. How large of a sample is required? B b. How large of a sample would be necessary if no estimate were available for the proportion supporting current policy? (Round intermediate values to 3 decimal points. Round your answer up to the next whole number.)
The sample size for part A is 4025, and the sample size for part B is 4160
What is the margin of error(MOE)?It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
\(\rm MOE = Z\times \dfrac{s}{\sqrt{N}}\)
Where Z is the z-score at the confidence interval
s is the standard deviation
N is the number of samples.
MOE = 0.02
99% level of confidence
a = 1 - 0.99 = 0.01
Z(a/2) = 2.58
The president's political advisors estimated the proportion supporting the current policy to be 0.41.
A) p = 0.41
\(\rm N = p(1-p)(\dfrac{Z_{\alpha/2}}{MOE})^2\)
\(\rm N =0.41(1-0.41)(\dfrac{{2.58}}{0.02})^2\)
N = 4025.45 ≈ 4025
B) How large of a sample would be necessary if no estimate were available for the proportion supporting the current policy
\(\rm N =0.5(1-0.5)(\dfrac{{2.58}}{0.02})^2\)
N = 4160
Thus, the sample size for part A is 4025, and the sample size for part B is 4160

a. Suppose a BMW dealer in Fullerton, CA is trying to calculate the probability of his car sale for next week. The dealer knows that the sale of car is normally distributed with mean 50 and variance 9. The variance 9 was calculated from the weekly car sale data of 20 weeks, as the population variance is not known to the dealer. What is the probability that the dealer will sell 51 or more cars next week? (Hint: use t distribution) (15)
Answer:
0.45576
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Standard Deviation = √variance
Mean = 50
= √9
= 3
z = 51 - 50/3
= 0.11111
Probability value from Z-Table:
P(x<51) = 0.54424
P(x>51) = 1 - P(x<51)
= 1 - 0.54424
= 0.45576
The probability that the dealer will sell 51 or more cars is 0.45576
Why should you avoid investing all your money in familiar stocks?
A.
to increase the value of your returns
B.
to research unfamiliar industries that might reveal good investment opportunities
C.
to avoid selling at a loss
D.
to avoid diversifying into multiple investment options
Answer:
B.
Step-by-step explanation:
The main reason for this is to research unfamiliar industries that might reveal good investment opportunities. When you conform to what you know, you fall into a comfort zone. This prevents you from taking the time to investigate and learn new things. In this scenario, investing everything in familiar stocks will prevent you from looking for new investment options in different industries which could have led to incredible investment opportunities. Therefore, it is a better choice to invest a large portion in safer familiar stocks but leave a certain percentage for riskier and newer investments.

A) Find an equation for the line perpendicular to the tangent line to the curve y=x^3-4x+6 at the point (2,6)
-The equation is y=
b) What is the smallest slope on the curve? At what point on the curve does the curve have this slope?
-The smallest slope on the curve is
-The curve has the smallest slope at the point
c) Find equations for the tangent lines to the curve at the points where the slope of the curve is 8.
Answer:
f(x) = x³ - 4x + 6
f'(x) = 3x² - 4
a) f'(2) = 3(2²) - 4 = 12 - 4 = 8
6 = 8(2) + b
6 = 16 + b
b = -10
y = 8x - 10
b) 3x² - 4 = 0
3x² = 4, so x = ±2/√3 = ±(2/3)√3
= ±1.1547
f(-(2/3)√3) = 9.0792
f((2/3)√3) = 2.9208
c) 3x² - 4 = 8
3x² = 12
x² = 4, so x = ±2
f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6
6 = -2(8) + b
6 = -16 + b
b = 22
y = 8x + 22
f(2) = 6
y = 8x - 10
The equation perpendicular to the tangent is y = -1/8x + 25/4
-The smallest slope on the curve is 2.92
The curve has the smallest slope at the point (1.15, 2.92)
The equations at tangent points are y = 8x + 16 and y = 8x - 16
Finding the equation perpendicular to the tangentFrom the question, we have the following parameters that can be used in our computation:
y = x³ - 4x + 6
Differentiate
So, we have
f'(x) = 3x² - 4
The point is (2, 6)
So, we have
f'(2) = 3(2)² - 4
f'(2) = 8
The slope of the perpendicular line is
Slope = -1/8
So, we have
y = -1/8(x - 2) + 6
y = -1/8x + 25/4
The smallest slope on the curveWe have
f'(x) = 3x² - 4
Set to 0
3x² - 4 = 0
Solve for x
x = √[4/3]
x = 1.15
So, we have
Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6
Smallest slope = 2.92
So, the smallest slope is 2.92 at (1.15, 2.92)
The equation of the tangent lineHere, we set f'(x) to 8
3x² - 4 = 8
Solve for x
x = ±2
Calculate y at x = ±2
y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)
y = (2)³ - 4(2) + 6 = 6: (2, 0)
The equations at these points are
y = 8x + 16
y = 8x - 16

Since insulin u-100 is 100 units/mL,which of the following shortcuts can be used to convert a dose of u-100 insulin given in units, to mL
Answer:
The shortcuts is
Divide number of units by 100
Step-by-step explanation:
From the question we are told that
insulin u-100 is \(L = 100 \ unit /mL\)
From the data given above we see that
100 units of insulin u-100 is contained in 1 mL
So 1 unit of u-100 is contained in x mL
=> \(x = \frac{1}{100} \ mL\)
This means that a unit of insulin u-100 occupies \(x = \frac{1}{100} \ mL\)
So we can represent a single unit of insulin u-100 as \(\frac{1}{100} \ mL\)
Now if 1 unit of insulin u-100 is represented as \(\frac{1}{100} \ mL\)
Then y unites of insulin u-100 is represented as z
So
\(z = \frac{y}{100} \ mL\)
From the above calculation we can see that the shortcuts to convert u-100 insulin given in units, to mL is to divide number of units by 100

n=
Answer:
\(n=\frac{3f-8}{10}\)
Step-by-step explanation:
So we have the equation:
\(\frac{3}{4}f-\frac{5}{2}n=2\)
First, remove all the fractions by multiplying by the LCM of the denominator.
The LCM of 4 and 2 is 4. Thus:
\(4(\frac{3}{4}f-\frac{5}{2}n)=4(2)\)
Distribute:
\(4(\frac{3}{4}f})-4(\frac{5}{2}n})=4(2)\)
Simplify:
\(3f-10n=8\)
Subtract 3f from both sides:
\((3f-10n)-3f=(8)-3f\\-10n=8-3f\)
Divide both sides by -10:
\(n=\frac{8-3f}{-10}\)
Divide by -1:
\(n=\frac{3f-8}{10}\)
And this is our answer :)
n = (3f - 8)/10
Step-by-step explanation:3f/4 - ²⁾5n/2 = ⁴⁾2
3f - 10n = 8
3f - 8 = 10n

Answer:
33.3%
Step-by-step explanation:
The selling price of £42 is (1 +40%) times the total purchase price.
1.40 × purchase price = £42
purchase price = £42/1.40 = £30
The total profit is 40% of this, so is ...
£30 × 40% = £12
The purchase price of the skirt is ...
total cost - glove cost = skirt cost = £30 -3 = £27
The profit on the skirt is ...
total profit - glove profit = skirt profit = £12 -100% × £3 = £9
Then the percentage profit on the skirt is ...
skirt profit % = skirt profit / skirt cost × 100% = £9/£27 × 100% = 33.3%
The percentage profit on the cost of the skirt was 33.3%.

A store gives a 15% discount to reward members? What is the discount on $215 worth of merchandise
To find the discount on $215 worth of merchandise with a 15% discount, you can use the following steps:
1. Calculate the discount amount as a percentage of the original price:
discount amount = original price x discount rate
discount amount = $215 x 0.15
discount amount = $32.25
2. Subtract the discount amount from the original price to find the sale price:
sale price = original price - discount amount
sale price = $215 - $32.25
sale price = $182.75
Therefore, the discount on $215 worth of merchandise with a 15% discount is $32.25. The sale price after the discount is $182.75.

The value of θ is 60° and the the value of the equation sec 60° = 2
What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the angle be represented as θ
Now , given that the angle θ is acute
Acute angles measure less than 90 degrees
So , the value of θ < 90°
when the value of sec θ = 2
cos θ = 1/sec θ
So , cos θ = 1/2
The value of θ when cos θ is 1/2 is when the angle θ is 60°
Therefore , the value of θ is 60° and sec 60° = 2
Hence , The value of θ is 60° and the the value of the equation sec 60° = 2

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
The coordinates of the vertices of the triangle RST:
R(-5,-9), S(6,-3), T(-1,6)
The coordinates (x, y) of the centroid of a triangle.
x = (a + c + e) / 3
y = (b + d + f) / 3
Where (a, b), (c, d), and (e, f) are the coordinates of the vertices of a triangle.
Now,
(a, b) = (-5, -9)
(c, d) = (6, -3)
(e, f) = (-1, 6)
The coordinates (x, y) of the centroid of a triangle is (0, -2).
x = (-5 + 6 - 1) / 3
x = 0
y = (-9 - 3 + 6) / 3

The volume of the composite figure is
4095 cubic ydHow to find the volume of the composite figureThe volume is calculated by dividing the figure into simpler shapes. and adding the individual volumes
The simple shapes used here include
trapezoid andrectangleVolume of rectangle = length x width x depth
= 30 * 9 * 7
= 1890 cubic yd
Volume of trapezoid = 1/2 (sum of parallel lines) x height x depth
= 1/2 (30 + 19) x 10 x 9
= 2205 cubic yd
Total volume
= 1890 cubic yd + 2205 cubic yd
= 4095 cubic yd

How do I find GBA and show all the work
Answer:
Angle ACB = 44°
There are two ways to solve it. Both are right
Solution number 1
From triangle ABC
angle BAC = 180°-(102° +44°) = 36°
Because BG is parallel with AC
Then angle GBA = angle BAC = 34°Another solution
The sum of angles in the shape AGBC = 360°
So angle GBC = 360 - (90 + 90 + 44 + 102) = 34°
